MULTI-COMPONENT TUBULAR COUPLING FOR WELLHEAD SYSTEMS

摘要

A multi-component tubular coupling is provided for wellhead assemblies. In one embodiment, the multi-component tubular coupling may include a first tubular member, a landing ring, and a second tubular member. The second tubular member may include internal threads, lock screws, or any combination thereof to couple to a wellhead component. In another embodiment, the multi-component tubular coupling may only include the first tubular member and the landing ring. In such an embodiment, a wellhead component may be secured to the coupling via lock screws.
